What Is a Segmented Diamond Blade and When Should You Use One?

A segmented diamond blade is one of the most widely used cutting tools in construction and masonry. Known for its speed, durability, and cooling efficiency, a segmented blade is designed to handle tough materials like concrete, asphalt, brick, and stone. But how do segmented blades differ from continuous rim or turbo blades, and when should you use one?

In this blog, we’ll explore what segmented diamond blades are, their benefits, the best applications, and how they compare to other blade types.

What Is a Segmented Diamond Blade?

A segmented diamond blade is built with individual sections, or “segments,” embedded with synthetic diamond particles. These segments are separated by gullets, small spaces that allow for airflow, cooling, and debris removal during cutting.

This design makes segmented blades ideal for aggressive, high-speed cutting. Unlike continuous rim blades, which create smoother edges, segmented blades are designed for efficiency and durability on the hardest surfaces.

So, why use a segmented diamond blade? Because when speed, power, and versatility are more important than a polished edge, no other blade type performs as well.

Benefits of Segmented Blades

The advantages of using a segmented diamond blade go beyond its rugged design. These blades are chosen by professionals for several reasons:

• Faster cutting: The open gullets help the blade cut aggressively, saving time on large projects.
• Cooling efficiency: Cooling holes circulate air to reduce heat, prevent warping, and extend blade life.
• Durability: Segmented blades withstand tough, abrasive materials without wearing down quickly.
• Versatility: They can be used for both wet and dry cutting in a wide variety of applications.

Common Applications of Segmented Diamond Blades

Segmented blades are designed to perform well in some of the toughest jobsite conditions. Contractors rely on them for:

• Concrete and reinforced concrete: Sidewalks, driveways, foundations, and slabs.
• Masonry: Brick, block, and stone cutting for construction or landscaping.
• Asphalt: Road and pavement repair projects.

Why Segmented Diamond Blades are Beneficial for Pro Contractors & Municipal Crews

Segmented diamond blades are ideal for professional contractors and municipal crews because they deliver fast, durable, and versatile cutting performance on tough materials like concrete, asphalt, masonry, and pipe.

Here are the key reasons:

Fast, Aggressive Cutting

Deep, Efficient Cuts: The segmented rim features wide gullets (gaps) that quickly remove debris and allow for aggressive cutting, which saves time on large projects such as road repairs, curb cuts, and pipe installations.

Less Friction & Heat: The open segments reduce contact with the material, lowering friction and allowing higher cutting speeds compared to continuous-rim blades.

Cooler Operation & Longer Blade Life

Superior Heat Dissipation: The gaps between segments allow air to circulate and keep the steel core cool, reducing the risk of overheating or blade warping.

Extended Lifespan: By staying cooler and resisting thermal stress, the blade maintains its diamond bond longer, meaning fewer blade changes and lower cost per cut.

Heavy-Duty Durability

Handles Reinforced Materials: Segmented blades are strong enough to cut through concrete with rebar, cured asphalt, and hard masonry without chipping or cracking.

Built for Jobsite Demands: Their robust design withstands the rigors of municipal street work, utility trenching, and large commercial projects.

Versatility Across Applications

Wet or Dry Cutting: They can be used with water for dust suppression and cooler cutting or run dry when water is not available—ideal for street repairs or utility work.

Multiple Materials: From ductile iron pipe to sidewalks and curbs, one blade can often handle the full range of municipal or construction needs.

How to Choose the Right Diamond Blades

Not every segmented diamond blade is the same. Choosing the right one depends on the job and the equipment. Factors to consider include:

• Blade size: Match the diameter to your saw, whether handheld or walk-behind.
• Wet vs dry cutting: Wet cutting extends blade life and reduces dust, while dry cutting offers convenience.
• Bond hardness: A softer bond cuts harder materials, while a harder bond cuts softer, abrasive materials.
• Application: Concrete, asphalt, masonry, or stone may require different segment configurations.

Safety Considerations for Segmented Diamond Blades

Safety is always a priority when working with diamond blades. OSHA requires that walk-behind saws and grinders cutting silica-containing materials be equipped with water delivery systems that apply water to the blade to suppress dust (OSHA 29 CFR 1926.1153).

NIOSH also emphasizes the effectiveness of wet cutting methods in reducing respirable crystalline silica, noting that water-fed tools significantly lower dust levels compared to dry cutting (NIOSH Silica Guidance).

Always wear proper PPE, including safety glasses or a face shield, hearing protection, respiratory protection when dry cutting or indoors, gloves, and steel-toed boots.

Frequently Asked Questions About Segmented Diamond Blades

Why use a segmented diamond blade?

For fast, aggressive cuts in concrete, asphalt, brick, and stone where a smooth finish is not the priority.

Can segmented blades cut tile?

While possible, it is not recommended. Continuous rim blades are better for tile because they provide chip-free edges.

How long does a segmented blade last?

Lifespan depends on material, blade quality, and whether you cut wet or dry. In general, wet cutting extends blade life significantly.

Which is better: segmented or continuous?

Neither is “better” overall. Segmented blades are better for concrete and masonry, while continuous rim blades are better for tile and delicate materials.

Final Thoughts on Segmented Diamond Blades

A segmented diamond blade is one of the most reliable, versatile tools for contractors, landscapers, and masons. With unmatched durability, cutting speed, and cooling efficiency, these blades are essential for concrete, asphalt, and masonry jobs.
